Horsetail Fall has become a photographic phenomenon. This skimpy waterfall, a trickle compared to the thundering volume of nearby Yosemite or Bridalveil Falls, attracts hundreds or even thousands of photographers to Yosemite Valley each February. What makes this little fall so visually appealing is its unique location. Descending from a high shoulder of El Capitan, it catches the light perfectly at sunset for about ten days in February. With enough flow and the right light, this sliver of falling water glows neon orange.
